Teredo/miredo is not the most robust IPv6 connectivity, but it's easy and free, and if it works, it can also work if you roam around.

Teredo/miredo IPv6 addresses are recognizable by their 2001:0:-address. Please note the :0: after the 2001! IPv6 address with another, non-zero value immediately after the 2001, are 'normal', non-teredo IPv6 addresses.

Windows

Windows 7 and Vista have teredo built-in and activated. In my experience it works on a plain Windows install, also if Microsoft Security Essentials is installed.
Software and configs that seem to disable teredo IPv6-connectivity are:
1) other, non-Microsoft virusscanners and firewalls,
2) corporate firewalls and proxy servers
3) VMware
4) (unconfirmed) having a straight, non-NAT Internet connection. Windows will then possibly use 6to4/6over4, recognizable by it's 2002: address

You can check the teredo status with the following commands, which you should run from a terminal opened with the Run -> "CMD" command:

On Linux, you should install "miredo". On Ubuntu, you can do that install using "sudo apt-get install miredo".
After installing miredo, your "ifconfig" should then show a 2001:0: address at the "teredo" interface.

There's also reader.ipv6.xsnews.nl, which is free, needs an account, and/but Xsnews has stopped giving away accounts for this server.

Remote access to SABnzbd's webinterface via IPv6

To get IPv6 access to SABnzbd's webinterface, you need to have IPv6 working, and you need to fill out "::" (without the quotes) in SABnzbd -> Config -> Server at the field "SABnzbd Host". Press Save Changes, and then restart SABnzbd.
On Linux, you can now access your SABnzbd's webinterface on it's public IPv6 address, so something like http://[2001:0:.....]:8080/
Please note: on Windows, you can then access SABnzbd's webinterface only via the IPv6 address, so http://[::1]:8080/ or possibly http://ip6-localhost:8080/ . It seems Windows is refusing "unexpected" connections from remote systems; this way Windows is mimicking IPv4-behind-NAT behaviour.

(By the way: your speedtest-test is usefull and showes a fine result, but it is not mentioned on that IPv6-page?)

After an initial question (I'm a newbe on SABnzbd) Sander proposed to use IPv6 (teredo/miredo) for a couple of reasons; such as better performance on free newsservers (as newszilla6.xs4all.nl). I said that I use SABnzbd especially at home. I gave away that I'm using Windows XP + Service Pack 3 (SP3) and that the result of the speedtest was:

My questions thereafter were:
1) How difficult is the installation of teredo. Is it a big and drastical installation and which positive results may I expect afterwards?
2) I plan installing fibrenet at home and asked if this will also give me more speed in the future. I'm also using a wireless network at home.

Open a CMD-box, and type in the two commands mentioned in the manual above (and once again here below). Then, after about 30 seconds you know whether IPv6 works on your systems; visit http://test-ipv6.com/ and that site will tell you...

Now you can fill out an IPv6-only newsserver, for example newszilla6.xs4all.nl at Config -> Server (so maybe http://localhost:8080/config/server/ ), 3 connections, no account or password. Click on Save, and then test server. What does SABnzbd say to you?

Following my first tests with the IPv6-newsserver newszilla6.xs4all.nl; the speedburst is enormous:
- with IPv4 reader.xsusenet.com (1) only between 53 and 124 KB/sec.
- with (1) + newszilla6.xs4all.nl between 414 and 879 KB/sec.
P.S.: of course, the retention period of newszilla6.xs4all.nl is much lower.

In the next days I'm going to test if it is usefull adding suplemental newsservers... Are there other free IPv6 newsservers?

Coincidentally today I read an article, in an old EOS-magazine (spring 2011), on the necessary changes from IPv4 to IPv6. As a result, I understand better what there is all behind.

Tomorrow Telenet will install fibrenet at home... I'm very curious if this will result in an additional speed.

Congratulations. And enjoy IPv6. See my first post in this thread to see another free IPv6 newsserver.

A question for you: are you using a virusscanner? If so, which type? And a firewall on your PC?
Reason of my question: virusscanners / firewalls other than Microsoft Security Essentials have the strange habit of blocking IPv6 traffic. So I wonder what you use.
